' i lhis inventinr'elates to roller bearings [fer drawers and more particularly to" bear? 7 'ings of this type that. embody casings H adapted to be recessed into the guides for "5' thendrawerseand rollers supportedin the I casings byfranti-friction halls.

adapted t9 maintain the anti-friction balls instraight rows at opposite sides of the axis of the roller. I
